AI cloud architecture diagram generator.

Read the configuration, not the account

Terraform, CloudFormation, Bicep, Pulumi and Kubernetes manifests all describe infrastructure precisely, and all of them are files. Reading files rather than connecting to an account means no credentials, no read-only role to provision, and the ability to diagram an environment you have no access to. A tool that wants production access to draw a picture is a poor trade.

How Lucid Train draws one

Describe what you want, or point it at a repository. The agent emits a semantic graph of nodes and edges with no coordinates, and the ELK layout engine computes positions and orthogonal routing. That separation is the reason the output cannot come back with boxes overlapping or arrows crossing through cards, which is the characteristic failure when a language model is asked to place things on a canvas itself. It also means editing is editing the graph: change a component and the layout re-solves rather than drifting out of alignment.

Multi-cloud in one diagram

Plenty of real systems span providers, usually not by design: object storage in one, a managed database in another, an identity provider somewhere else. Because tiers are the organising principle rather than provider boundaries, a diagram can hold all of it and still read clearly, with provider showing up as the icon rather than as a container.

Icons are bundled, so it works offline

Service logos ship with the app rather than being fetched. A diagram that silently loses its icons on a plane or inside an air-gapped network is one you cannot rely on for a review, and that is a surprisingly common failure in browser-based tools.

Local, offline, your models

It runs as a desktop application. Against a local Ollama model the whole thing works offline with no API key and no telemetry, which is the practical difference from every browser-based diagram tool: your architecture never leaves the machine.
